CHARLES RODERICK AND THERON L.

KNAPP, OF WOODSTOCK, ILLINOIS, ASSIGNORS TO THE OLIVER TYPEWRITERCOMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

MEANS FOR SECURING TYPE-WRITERS TO BASE-BOARDS.

Specification of Letters Patent.

Patented May 8, 191?.

Application filed July 1, 1910. Serial No. 569,960.

United States, and residents of Woodstock,

in the county of McHenry and State of Illinois, have invented certainnew and useful Improvements in Means for Securing Type- VVriters toBase-Boards;'and we do hereby declare that the following is a full,clear, and exact description thereof, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

This invention relates to typewriting machines and is more particularlyapplicable to machines of the Oliver type in which the shift-frame isprovided with two horizontal, transversely arranged guide-bars on whichthe paper-carriage rests and travels and in which said guide-barsproject at their ends beyond the shift-frame proper and extend laterallyoutside of the frame where they are supported from a base-board beneaththe machine frame. The type of Inachine referred to is illustrated inLetters Patent Number 904,207, of the United States, granted November17th, 1908, to

I Theron L. Knapp.

The object of the invention is to provide simple and eflicient means forsecuring the machine frame to the base-board which will, at the sametime, afford a cushion to decrease the shock and deaden the noise due tothe operation of the machine and will accurately maintain said machineframe 1n its proper relation with respect to the supports for theextended guide-bars.

In the drawings Figure 1 is a top plan view of a machine of the typedescribed, with the paper-carriage and type-keys removed and thevertical bars which support said type-keys shown in cross-section.

Fig. 2 is a partial vertical section on an enlarged scale through Fig. 1on the line 22 thereof.

Fig. 3 is a vertical section through Fig. 1 on the line 33 thereof.

Fig. 4 is a partial vertical section on an enlarged scale on the line4.-4L of Fig. 1.

Fig. 5 is a vertical section through Fig. l on the line 5-5 thereof.

As shown in the drawings, board; 11, the machine frame;

10 is the base- 12, the Shirt- 1d, the extended guide-rods for thepaper-carriage which are connected to the shift frame and projectlaterally beyond the machine frame; and 15, 15, 15, 15*, the supportsfor the ends of the guide-bars said supports being secured to thebaseboard. These parts are substantially as described in the patentreferred to and need no further description as they form no part frame;13,

- of the present invention.

The machine frame base 11 is preferably made hollow and has a top wall21 and an upright flange 21 16, 17 18, 19, indicate toe-clamps which aresecured to the baseboard 10 in position to engage against the uprightflange 21 of the base 11 of the machine frame. Said toe-clamps arepreferably arranged in pairs with one pair forward of and the other pairback of the transverse medial line of the machine, and with thetoe-clamps of each pair in a line parallel to the guide-bars 13, 14.Each of said toe-clamps consists of an angular piece of metal having ahorizontal member 16 which engages the top of the base-board, and anupright member 16 which engages the outer surface of the upright wall ofthe machine base. The horizontal members 16 are provided with holes forscrews 22 by means of which they are secured to the baseboard. It isapparent that the toe-clamps form rigid abutments rising from thebaseboard which will positively resist any tendency of the machine frameto twist or shift on the base-board in the operation of the shift-frame.

The base 11 is anchored or held to the base-board by the followingmeans: In the vertical plane of the longitudinal central axis of themachine frame, near the front of the same, there is secured to theunderside of the top 21 of the base, a lug 23, (see Figs. 1, 4; and 5).Said lug is preferably provided with lateral flanges 23 23 having holesor openings to receive screws 23", 23", which are threaded into the top21 of the base. 24: is a recess opening through the bottom of said lugand internally threaded to receive the upper end of a threaded bolt 25which projects upwardly from the base-board and is located in a verticalhole 26 in the baseboard. Said hole is enlarged at the bottom to form arecess 26 to receive the head 25 of the bolt and a washer 27 againstwhich said head directly bears. The base of the lug 23 is substantiallyon a level with the lower margin of the upright flange 21 of the baseand rests on' an elastic washer 28 interposed between its base and thetop of the base board 10. This construction efficiently anchors or holdsthe machine base at this point to the base board and at the game timeaffords a cushion bearing for said ase.

Similar anchoring and cushioning devices are located at the rear of themachine at points spaced equally on each side of the longitudinalcentral axis of the machine base (see Figs. 1 and 2). In this case theupright wall of the base is preferably thickened at the point ofanchorage to form a lug 33. Said lug is provided as before with avertical internally threaded recess 34; to receive a vertical threadedbolt 35 which projects upwardly from a hole 36 formed in the base-board.38 is the cushioning washer interposed between the base of the lug andthe top surface of the base-board. On account of the increased depth ofthe upright flange 21 at the rear of the base, the bolts 35 may be madelonger than the bolt 25.

It is apparent from the above description that the bolts 25, 35, 35 maybe drawn home so as to efliciently anchor the machine to the base-boardand hold it securely against overturning without impairing theefiiciency of the cushioning members 28, 38, 38, and that Copies of thispatent may be obtained for five cents each, by addressing the anytendency of the machine to twist or shift on the baseboard, madepossible by the elasticity of this anchorage, is prevented by thetoe-clamps 16, 17, 1S and 19.

We claim as our invention The combination of a typewriting machinehaving a base portion providedwith substantially upright side walls andfastener lugs rigid with said base portion, a base board, cushioningmembers interposed between said lugs and said base board for holdingsaid machine base out of contact with said board, fastener boltsextending vertically through said base board and said cushioning membersand engaging said lugs to loosely secure said machine base to said baseboard, and a plurality of abutments rigidly secured to said base boardand having upwardly projecting portions engaging the side walls of saidmachine base to securely hold the same against lateral movement whilepermitting a limited vertical movement thereof relative to said baseboard, substantially as described.

In testimony, that we claim the foregoing as our invention we aflix oursignatures in the presence of two witnesses, this 17th day of June, A.D. 1910.
